6. Setting Up Communication
Communicating with the Router Through Serial Ports
How to Make a Temporary Serial Connection
1 Locate the primary control card slot. The control card is accessed through the front of the router
when the router door is open. See your router user’ guide for details.
2 On the front of the control card, connect to the DE9 connection using a DE9 connector and a
serial cable set for EIA-232.
The following lists the wiring for the DE9 pin connectors for RS-232:
3 Connect the other end of the cable to the hardware running the UniConfig application using a
DE9 connector. (See Installing UniConfig on page 19.)
Router Serial ‘DIAG’ Port (Permanent Connection)
There are two permanent serial ports located on the router, labeled ‘DIAG’: one primary (‘PRI
CTRL’) and one secondary (‘SEC CTRL’). The primary control port connects to the primary con-
trol card. The secondary control port connects to the secondary (optional for redundancy) control
card. By default, the ports are typically set to 38400 baud, RS-232, but can be set to RS-422 using
UniConfig. (See
Updating Serial Communication Settings on page 30.)
If you are using a permanent serial port to communicate with UniConfig, it is best to set the com-
munications parameters to the highest baud rate possible to minimize the time required to down-
load the code.

Note The NV8288, NV8288-Plus and NV8500 Family routers have only a rear diag-
nostic port. This enables the rear port to double as a temporary connection to the
control card, as well as a permanent connection. See
